| Abstract: | The composite binder of dihydrate phosgypsum and fly ash (PGF) is a new kind of binder made from unpretreated phosgypsum, fly ash and activator. By means of XRD and SEM, this paper studies the proper proportion, curing method and system, and properties of PGF, as well as mechanical property tests and hydration heat, pH and pore structure determination . The appropriate alkali activation, strength development and curing, and the cause of improvement of waterproof property of PGF are analyzed as well. |
